Question

Square has a side lengths of 10a+4b what is the perimeter of the
square?

Answer 1

P = 40a + 16b

Explanation:

the perimeter of a square is the sum of its side lengths (s)

Since the 4 sides of a square are congruent (equal ) then

P = 4s = 4(10a + 4b) ← multiply each term in the parenthesis by 4

P = 40a + 16b
